To all whom it may concern: v

Be it known that we, ANTONIO GROssICI-rand PAOLO MATCOVICH, subjects of the Elm peror, King of Hungary, and residents of the 5 city of -Fiume, Hungary, in the Austro- Hungarian Empire, have invented certain new and useful Improvements-in Processes 'of Manufacturing Antiseptic Paper and the Like, applicable for use as bandages for ro'wounds and for hygienicand pr'cservati've purposes, (patented in GreatBritaimNo. 7 ,854, May 29, 1888; in Italy, No. 23,399, J uly24, 1888, with certificate of addition, No. 24,173, and prolongation, No. 24,174.; in France, N0.

1889, No. cocoon, and No. 53,79,1 and we (10 2o hereby declare that the following is a full,

' clear, and exact description of the same.

Thisinvention has for its object the preparation ofa new product called antiseptic paper. 1

' The elements used for the manufacture of antiseptic paper are linen and cotton, the

proportion being preferably about seventyfive per cent. of linen and twenty-five per cent. of cotton. The linen used for the purpose of giving the necessary strength of pure. First,'it is washed in an alkaline liquidcomposed of water andsodic and potassic hy- 4p dro'xide, in the proportion of thirty kilos of vdistilled water and one kiloof potassic hydroxide for every thirty kilos of pulp; second, it is afterward rinsed or washed in distilled water at'a temperature of about 90 to -1'00 cent-igrade; third, in order to completely purify the substance it is once more washed 'L with ten kilos of pure alcohol'and afterward t ,with 'distilled water; .fourth,after being thus washed. the pulp is treatedwith a solution composed of three parts of saturated chlorine, 5: water and one hundred parts of water, for the 'purpose of bleaching and purifying it, and

then rinsed in a large quantity of distilled water; fifth, such pulp is formed in to sheets of paper of any desired length in the ordinary or any suitable manner by any of the -well-' known machines-as. for instance, by being first compressedand then rolled between aseptic rolls heated by steam to a temperature of 120 centigrade. Su'ch paper being 66 .made up in rolls, it isltransferred into any suitable disinfectorsuch as those called- ,line, carbolic acid, thymol, mustard-oil, picric acid, boraciciacid, turpen tine-oil, and salicylic The process of soaking the aseptic paper in the antiseptic liquid may be as follows: The aseptic paper is spread upon suitable glass rol1s,which by revolving cause the same to pass into a chinaware bath containing the antiseptic liquid. The paper is then engaged by 8g other pivoted rolls, which deliverit out. The rolls can be moved by the ordinary rackwhcels.- 4 o The antisepticssmaybc used in the following proportion, namely: iodoform, from one go to .fifty per cent; ca'rbolic acid, five-to six per cent; corrosive sublimate, one per thousand; thymol, one fifty-thousandth .to one eighty-thousandth, and so on, according to the prescription and to the use for.which the paper isintended. 1 l

In order to render the paper more or less .soft and flegible, it is desirableito add-to the solution a certain percentage of glycerine or Vaseline. The percentage of glycerine which may be added to the antiseptic solution is from one to forty per cent.

The solution of the antiseptics is effected in alcohol and ether for the iodoforin, salol, and salicylic acid, while for the phenic acid and corrosive sublimate it. is elfected in water and alcohol. For the naphthaline it is effected in alcohol and ether.

All the water used must always be thoroughly pure and distilled, and also the glycerine, which is added in quantities varying from ten to twenty per cent, must be previously boiled for one hour.

The antiseptic paper can be advantageously used for bandages, dressing wounds, &c. It replaces advantageously gauze, wadding, .im-

pervious cloth, and all fabrics h therto used.

for surgical and other purposes. It can also he employed for various purposes, especially for preserving all kinds of matter which is liable to be injured byinsects, for preserving fruit, clothing, furs, tire. For instance, salieylicated paper is admirably suited for wrapping up oranges and lemons, and generally all kinds of fruits, for the purpose of better preserving them. Paper impregnated with phenic or carbolic acid can also be used for the same purpose, as well as for hygienic and other purposes-such as forming a layer under chamber-hangings, linin for beds, wrappers for parchments, paintings, engravings, drawings, valuable cloths, &c.

The antiseptic paper may be used as a substitute for lint after being cut into thin strips by suitable cutters. Such strips may be used for. surgical purposes, as also for packing fruits and for preserving clothing, furs, '&e.,' from moths.

\Vhat we claim asnew, and desire to secure by Letters Patent, is k 1. The herein-described process of manufacturing antiseptic paper, consisting in forming a pulp of linen and cotton, as described, then washing the same in a solution of sodic and potassic hydroxide, then washing and purifying the pulp, then treating it with chlorine water, and then forming the pulp into sheets, substantially as and for the purposes set forth,

2. The herein-described process of manufacturing antiseptic mper,consisting in forming a pulp of linen and cotton, as described, then washing the same in a solution of sodic and potassic hydroxide, then washing and purifying the pulp, then treating it with chlorine water, then forming the pulp into sheets, then disinfecting the paper at a moist heat, and then treating it with an antiseplic bath, substantially'as and for the purposes set forth.

3. The herein-described process of manufaeturing antiseptic paper, consisting in forming a pulp of linen and cotton, as described, then washing the same in a solution of sodie and potassic hydroxide; then washing and purifying the pulp, then treating it with chlorine water, then forming the-pulp Into sheets, then disinfecting the paper at a moist heat, and then treating it with an antiseptic bath and with glycerine, substantially as set forth.

In witness whereof we have hereunto set our hands in presence of two witnesses.
